1.1 RADIO AND TV INTERFERENCE
The Model 2121/2135Cgenerates and uses radio frequency ener-
gy, and if not installed and used properly—that is, in strict accordance
with the manufacturer’s instructions—may cause interference to radio
and television reception. The Model 2121/2135Chas been tested and
complies with the limits for a Class A computing device in accordance
with the specification in Subpart J of Part 15 of FCC rules, that are
designed to provide reasonable protection from such interference in a
commercial installation. However, this is no guarantee that interfer-
ence will not occur in a particular installation. If the Model 2121/2135C
does cause interference to radio or television reception, which can be
determined by disconnecting the unit, the user is encouraged to try to
correct the interference by one or more of the following measures:
moving the computing equipment away from the receiver, re-orienting
the receiving antenna and/or plugging the receiving equipment into a
different AC outlet (such that the computing equipment and receiver
are on different branches). In the event the user detects intermittent or
continuous product malfunction due to nearby high power transmitting
radio frequency equipment, the user is strongly advised to use only a
shielded twisted pair data cable that is bonded to metalized external
outer shield plugs at both ends. The use of a shielded cable satisfies
compliance with the Electromagnetic Compatibility (EMC) directive.
1.2 CE NOTICE
The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU). A Certificate of Compliance is available by contacting Patton
Technical Support.
